Answer 1

您不能在%let last_saturday = intnx ('week.7', today()-1, 0); %let last_saturday = %sysfunc(intnx (week.7, %sysfunc(today())-1, 0), yymmdd10.); %put NOTE: &last_saturday; %let last_saturday_sq = %sysfunc(quote(&last_saturday,%str(%'))); %put NOTE: &last_saturday_sq; proc sql; … connection to … (cast &last_saturday_sq as DATE) as asof … 视图操作中执行此操作，也不能使用域元组右侧的字段，因为将没有上下文来提供该值。为了完成它，您将需要将按钮更改为object类型，并使用关联的python方法返回具有所评估的所需域值的action dict，以便该域仅包含其右侧元组的值。点赞（查看按钮的新类型和名称）：

action_purchase_orders

在您的<button type="object" name="action_purchase_orders" class="oe_stat_button" icon="fa-list-alt" attrs="{'invisible':[('purchase_order_count', '=', 0)]}"> <field name="purchase_order_count" invisible="1"/> <field name="purchase_order_ids" string="Purchase Orders" widget="statinfo" help="Purchase orders"/> </button> 模型中，定义方法purchase.form，例如：

action_purchase_orders

Answer 2

添加与采购订单的关系

class PurchaseOrder(models.Model):
_inherit = 'purchase.order'

   purchase_form_ids = fields.Many2many('purchase.form', 'purchase_form_purchase_order_rel', 'purchase_order_id', 'purchase_form_id', 'Purchase Orders')

并将操作视图更改为

<record model="ir.actions.act_window" id="action_purchase_orders">
    <field name="name">Purchase Orders</field>
    <field name="type">ir.actions.act_window</field>
    <field name="res_model">purchase.order</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form</field>
    <field name="domain">[('id', 'in', purchase_form_ids.ids)]</field> 
</record>
